VALVE-COCK.

SPECIFICATION forming part of Letters Patent No. 315,234, dated April 7, 1885.

Application filed May 8, 1884. (No model.)

To aZZ wh am it may concern:

Be it known that I, HENRY J. H. BROOKS, of Bloomfield, Essex county, New Jersey, have invented a new and Improved Valve-Cock, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved valvecock of simple construction, in which the globeis dispensed with, and which is so constructed that the flow of the steam, water, &c., is not interrupted by projections, 82c.

The invention consists in the construction and arrangement of parts, as will be hereinafter fully described and claimed.

Reference is to be had to the accompanying.

drawing, forming part of this specification, in which a longitudinal sectional elevation of my improved valve-cock is shown.

Two disks, A and B, are each provided wit an oblique tubular neck, A and B, respectively, which necks are screw-threaded at the outer ends, and adapted to be coupled to pipes, 850. The disk A is provided with a central aperture, 0, having beveled edges, and forming a seat for a valve, D, held on a screwthreaded stem, E, held in a tubular projection or neck, F. The valve-stem E is provided at the end with the usual hand-wheel, G. The

as the necks A B form a continuous straight passage when the disks A B are united. The l l l 35 1,

disks are clamped firmly together by means of screw bolts and nuts.

The Valve-cock is simple in construction, it

does not obstruct the passage of the watery steam, &c., and it is not apt to get out of order.

I cast a sleeve, F, of block-tin in the neck F, and cut the thread in the said block-tin so that it will fit closely on the thread of the stem. If the thread inthe neck wears out, it can easily be replaced by another by removing the block-tin core. The edge of the valve and the edge of the seat are slightly curved,

as shown, so as to cause them'to fit better andwith the valve D, and an operating-handle,

substantially as set forth.
